Letters Patent No. 100,178, dated February 22, 1870. l

The Schedule referred to in these Letters Patent and making part o theaame To all whom it may concern Be it known that I, F. B. MORSE, of Plantsville, in the county of Hartford, and State of Connecticut, have invented a new Improvement in Dies for .Forging King- Bolts; and I do hereby declare tile following, when taken in connect-ion withthe accompanying drawings and the letters of reference marked thereon, to he a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent m- Figure 1, a perspective view of the lower part of the first die Figure 2, a perspective view of the upper part, inverted;

Figure 3, the blank before the operation of the dies;

Figure 4, an under-side view of the bolt after the operation of the dies;

Figures 5 and 6, the trimming dies; and in Figure 7, an under-side view, with the bolt complete and trimmed.

This invention relates to an improvement in dies for forging king-bolts for carriages, the lobject being to produce such bolts in 'the desired s hape without welding, and at a single heat; and

The invention consists in the construction of a die so as to strike into the divided head of' the blank and form the clip, and spread the base of the clip so as to afford a larger bearing to strengthen the bolt laterally.

The blank, as seen in fig. 3, is drawn to form the boltA in the usual manner, and the head divided into two parts, B B. lhe blank, then heated, is placed into the'die, seen in fig. 1, formed to receive the bolt in the center, and its two sides, forming a V- shape, are each cut into the desired form for the two parts of the clip, and at the center, as ata a, spread laterally, so

as to give a longitudinal transverse beariug'to the head of the bolt.

The bolt, placed in the lower die (`J,tl1e upper part D corresponding to the V-shape of the lower part, is struck down into the divided part of the head, spreading Aand forcing the two parts into eachv side of the die, and the head extending out into the parts a n., the upper side of the head will be dat and of V-shape, corresponding to the part tig. 2 of the die. The bolt thus formed is then -placed into theme, tig. 5, and adjusted so as, by means of the part, iig. 6,'dropping thereinto,

' will trim the edges of the clip and the head,vcutting1 away the fin formed by the first operation, leaving the bolt complete as an article of manufacture, and as shown in tig. 7.

By this construction the head is spread, as at b, giving a lateral bearing t-o support and` strengthen the bolt. The bolt is then ready for market, and is adapted to further use .by consumers in the usual manuerjor this class of bolt-s.

I prefer to form the clip part or ends of the clip as I have shown and described, but it will be observed that the principal object of my invention, that is, the spreading of the head of' the bolt, would be Vaccomplished by the central portion of the dies only; that is, the object would be accomplished were the upper part of the dies moved down to the broken line, iig. 1. Thus, it will be observed, by a single heat, and practically by one operation, the head ot' the bolt and the clip are formed in the most perfect manner. Y

I claim as my invention- .1. lhe V- shaped die C D, constructed as described, so as to form the head ofv king-bolts at one operation.

2. Thetrimmiug dies, constructed as described, to

. trim the surplus metal from the head of king-bolts.

F. B. MORSE.
